Embodiment Construction

[0037] 1 to 4 show an analysis system 1 according to the invention with an analysis device 2 and a test element 3 . The analysis device 2 has a measurement and evaluation unit 4 and preferably an output unit 5 , to which analysis results 6 or error signals determined by the measurement and evaluation unit 4 are output.

[0038] The output unit 5 can display the analysis result 6 in the form of an optical signal, for example in the form of a numerical value, such as a glucose value, or in the form of various symbols. In addition, a sound output of the result is also possible. The output unit 5 can provide further information in addition to the analysis result 6, for example successful measurements can be output in clear text or in the form of a signal tone, just as error signals can also be output in clear text or in the form of a signal tone. Additionally, additional information can be displayed to the user.

[0039] The analytical device 2 as shown in FIGS. 1 to 4 optionall...

Abstract

An analysis system for determining an analyte of a body fluid comprises a test element and an analysis instrument having a measurement and evaluation unit. The test element has a sample application zone and two analysis zones and a reagent system, whose reaction with the analyte results in a detectable change characteristic for the desired analytical result. The measurement and evaluation unit comprises two analog measuring units, in each of which an analog measurement signal corresponding to one of the analysis zones is generated, two analog-digital converters for digitizing the analog measurement signal, a comparator unit for comparing control data values based on the digitized measurement signals, and a final processing unit, in which, if the determined deviation between the control data values of the digitized measurement signals is less than a predefined value, at least one of the control data values is allowed to pass for further processing into the desired analytical result.

Description

technical field [0001] The present invention relates to an analytical system for determining an analyte in a body fluid, comprising a test element having a reagent system whose reaction with the analyte results in a detectable change in the characteristic of the desired analytical result, and comprising a Analytical instruments for measurement and evaluation units. Background technique [0002] Analytical systems for determining analytes in body fluids using disposable test elements, test carriers or test strips are known in the prior art. This type of system is used to determine the concentration of various analytes. For example, determining the glucose level or cholesterol level in the blood. [0003] The test element typically comprises a reagent system consisting of one or more reagents, the reaction of which with the sample fluid results in a detectable change measurable by the analytical system. In a photometrically determined operating analytical system, as a react...
